ROTARY PUMP Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed December 9, 1907. Serial No. 405,800.

To all whom it may concern:

Be it known that I, 'IrIoMAs R. Harron, citizen of the United States, residing at Mount Vernon, in the county of Skagit and State of \Vashington, have invented certain new and useful Improvements in Rotary Pumps, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to improvements in rotary pumps; and the object of such improvements is to produce a pump of this character which will be of simple and inexpensive construction and which will be effective in action and capable of being operated with a small consumption of power.

With these ends in view the invention consists in the novel construction and adaptation of devices as will be hereinafter described and claimed.

In the drawings, Figure 1 is a transverse vertical section of a pump embodying the invention; Fig. 2 is a side elevation of the same with the casing-head removed without the attached eccentric-member, which is shown in section; Fig. 3 is a detail cross sectional view taken through 33 of Fig. 2; and Fig. 4 is a perspective view of a detached pump vane and connected parts.

The reference numeral 5 designates the pump -casing of a substantially circular shape, provided with a suitable supporting base, such as 6, and has a peripheral flange 7 whereby it is joined by securing bolts 8 with a head 9. The casing is provided with a cylindrical chamber 10 which communicates, preferably at the bottom, with waterintake and discharge pipe-connections 11 and 12, or vice versa. These connections are arranged tangentially of said chamber and that they may pass each other they are olfset from the medial plane, one of them being illustrated as formed partly within the head, see Fig. 1.

From such relative disposition of these pipe connections with respect to the pump chamber it will be apparent that the course taken by the fluid in its travel through the pump is looped, so to speak, and that, too, without any abrupt turns to interfere with its free flow.

Extending axially through the casing and the head, and journaled in suitable bearingboxes 5 and 9 of the respective parts is a shaft 13 arranged to be driven from a motor through the medium of any Well known power transmission device.

Fixedly mounted upon the shaft and located within the casing-chamber is a wheel let of a diameter somewhat less than the diameter of said chamber but of a width upon the periphery approximating that between the head 5) and the casing end which is opposite thereto, thus affording a cavity 10 about the wheel which is of an annular shape excepting for a partition 5 at the bottom. Said wheel is bored to furnish radially arranged sockets 15 for a plurality of cylindrical plungers 16 and in the radial planes of the respective plungers the wheel is slotted, as at 17, to accommodate a corresponding number of vanes 18. These vanes are rigidly connected with the respective plungers and of widths so as to make close sliding fit between the opposing sides of said annular cavity, while their depths are such as to extend from within the slots radially across said cavity when they are protruded to their maximum extent. as illustrated at the top of Fig. 2. Positioned within a recess 9 of the casing-head and fixedly connected to the latter is a cylinder 19 with its axis disposed in the same vertical plane with and above the axis of the shaft 13. Rotatable upon this eccentric-cylinder, or eccentric as it will be hereafter designated, is a sleeve 20 having at its inner end a collar 20 provided with a plurality of spaced apertures for the reception of the studs 21.

Connecting the respective studs with pins 16 fixedly secured to said plungers are links 22 which are actuated by their eccentric connections to reciprocate the said vanes in their slot seatings as they revolve.

The aforesaid journal bearings are provided with communicating receptacles such as the wells 5" and 9" for a supply of a lubricant means, such as a hole 23 extending from the receptacle 9 into the recess 9 of the head, whence the oil flows into the casing for supplying a lubricant to the contained movable parts.

Assuming that the wheel 14 is rotated in the direction indicated by the feathered arrow in Fig. 2, then through the action of the accompanying rotatin eccentric sleeve 20 and the connecting lin rs 22, the vanes 18 to the right hand of a vertical plane mw extended through the wheel-axis will be progressively protruded as they are carried with the wheel from their lowermost to their uppermost positions, after passing the latter, which coincides with such plane, they are gradually retracted until entirely sheathed within the wheel when they are again in proximity of said plane, and thus complete a cycle of revolution.

From the foregoing, and through the vanes being increasingly protruded in their ascent, it is obvious that the duty of the individual vanes will be accordingly increased until they exert their greatest elfectiveness in passing over the center of the pump and the water, or other fluid, being pumped has its speed accelerated until the fluid body has attained its normal velocity which thereafter maintained by the successively following vanes.

The pump is adapted to numerous useful applications, notably about manufacturing plants for pumping water in extinguishing fires; in an oil-pipe line where an uninterrupted flow is to be had therethrough; and for circulating condensing water in marine service.

In addition to its primary use the mechanism may be advantageously used as a Water meter with no material changes or alterations.

What I claim is 1. In a pump of the class described, in combination, a casing, a shaft extending transversely therethrough, a wheel carried by the shaft within the casing and formed with hollow radial socket members opening at one side thereof, plungers movable axially in said socket members, vanes carried by said plungers, said plungers each having a pin projecting through the side openings in the socket members, and means mounted at one side of the casing for rotation eccentrically of the shaft to cooperate with the pins in effecting axial movement of the plungers during the rotation of the Wheel.

2. In a pump of the class described, in combination, a casing having a centrally located extension at one side thereof, a shaft passed transversely through the casing and through the extension, a wheel carried by the shaft within the casing and formed With hollow radial socket members having alined longitudinally extending openings at opposite sides thereof, the openings on one side of the socket members extending from the hub of the wheel to the ends of said members and being of greater length than the openings in the other sides of said members, plungers movable axially in said socket members, each plunger being provided With a vane disposed in both of the openings and with a pin projecting laterally through the elongated opening, a stationary cylinder supported in the extension eccentrically of the shaft, a sleeve surrounding the cylinder and formed with a collar at one end thereof, and links pivoted to the collar and individually to corresponding pins on the plunger.

In testimony whereof I aflix my signature in presence of two witnesses.
